All you have to do is hit one thing and it will wipe out any savings people think they are getting from cold cranking and hitting the road with iced up windows.

Definitely. You see those people that clear out a tiny square in the windshield and then tear off down the road. It's too cold, you see, to stand out there and do the whole thing-- and they haven't got the TIME to sit there waiting for the engine to warm up and let the defrosters do it for them, so there they go, to heck with everyone else.

Good thing the block heater has made my windows clear off with minimal effort before I leave the driveway, so I can better see and avoid them.
